Nail salons are an important business and employment sector for recent immigrants offering popular services to a diverse range of customers across the United States. However, due to the nature of nail products and services, salon air can be burdened with a mix of low levels of hazardous airborne contaminants. Surveys of nail technicians have commonly found increased work-related symptoms, such as headaches and respiratory irritation, that are consistent with indoor air quality problems. In an effort to improve indoor air quality in nail salons, the state of New York recently promulgated regulations to require increased outdoor air and "source capture" of contaminants. Existing indoor air quality in New York State salons is unknown. In advance of the full implementation of the rules by 2021, we sought to establish reliable and usable baseline indoor air quality metrics to determine the feasibility and effectiveness of the requirement. In this pilot study, we measured total volatile organic compounds (TVOC) and carbon dioxide (CO) concentrations in 10 nail salons located in New York City to assess temporal and spatial trends. Within salon contaminant variation was generally minimal, indicating a well-mixed room and similar general exposure despite the task being performed. TVOC and CO concentrations were strongly positively correlated (ρ = 0.81; p < 0.01) suggesting that CO measurements could potentially be used to provide an initial determination of acceptable indoor air quality for the purposes of compliance with the standard. An almost tenfold increase in TVOC concentration was observed when the American National Standards Institute/American Society of Heating, Refrigerating and Air-Conditioning Engineers (ANSI/ASHRAE) target CO concentration of 850 ppm was exceeded compared to when this target was met.
美甲沙龙是新移民的一个重要商业和就业领域，在美国为各种各样的顾客提供受欢迎的服务。然而，由于美甲产品和服务的性质，沙龙空气中可能会含有低水平的有害空气污染物。对美甲技师的调查普遍发现，他们出现了与工作相关的症状增加的情况，如头痛和呼吸道刺激，这与室内空气质量问题相符。为了改善美甲沙龙的室内空气质量，纽约州最近颁布了法规，要求增加室外空气并对污染物进行“源头捕获”。纽约州沙龙现有的室内空气质量尚不清楚。在2021年全面实施这些规定之前，我们试图建立可靠且可用的室内空气质量基线指标，以确定该要求的可行性和有效性。在这项试点研究中，我们测量了纽约市10家美甲沙龙中的总挥发性有机化合物（TVOC）和二氧化碳（CO）浓度，以评估时间和空间趋势。沙龙内污染物的变化通常很小，这表明尽管在进行不同的工作，但房间内空气混合良好，一般暴露情况相似。TVOC和CO浓度呈强正相关（ρ = 0.81；p < 0.01），这表明CO测量有可能用于初步确定符合标准的可接受室内空气质量。当超过美国国家标准学会/美国供热、制冷与空调工程师协会（ANSI/ASHRAE）设定的850 ppm的CO浓度目标时，观察到TVOC浓度几乎增加了十倍，而当达到该目标时则不然。
